Abstract


We use Schwinger variational principle to evaluate excitation cross section of atomic hydrogen by proton impact at energy range between 2keV and 200keV. Contribution of the continuum near ionization threshold was introduced in a model using L2 method developed in a pseudo-space spanned by a set of Slater type functions. Our results were compared with those of Bouamoud (1988-1989) using 1s, 2s and 2p state of hydrogen atom.
